RTC battery
The internal RTC battery backs up the Real Time 
Clock (RTC) and calendar.
AC adaptor
The AC adaptor provides power to the system 
and recharges the batteries when they are low. 
It comes with a detachable power cord which will 
either have a 2-pin or 3-pin plug enclosure.
As the AC adaptor is universal, it can receive a 
range of AC voltages from 100 to 240 volts, 
however you should note that the output current 
varies among different models. Using the wrong 
adaptor can damage your computer. Refer to the 
 section in Chapter 2,

following Hard Disk Drive (HDD) types. The

Drive (SSD) instead of a hard disk drive.

Please note that part of the hard disk or Solid 
state drive’s overall capacity is reserved as 
administration space. Additional HDD/SSD drive 
sizes may be introduced.
In this manual, the word “HDD” or “Hard disk drive” also refers to the 
SSD unless otherwise stated.
SSD is a large-capacity storage media which uses Solid-State Memory 
in place of a magnetic disk of the hard disk.
Under certain unusual conditions of prolonged non-use and/or exposure to 
high temperatures, the SSD may be vulnerable to data retention errors.
